The call usually comes from a site that is already live. A villa gate in Jumeirah. A warehouse side entrance in JAFZA. A staff door in DIP. The Fanvil i20S has been working there for years, tied into the SIP system, opening the lock from reception, letting approved RFID cards through, and calling security when someone presses the door key. Now one unit needs support, matching, or replacement within the same installed design.

That is the right way to look at the Fanvil i20S in Dubai today. It is not a new-production door phone page for buyers choosing a fresh range from zero. Fanvil lists the i20S as discontinued from 22 December 2025, so availability must be checked before quoting. But many UAE sites still use it, and those sites often need the same model for maintenance, spares, phased work, or a like-for-like unit that keeps the existing wiring, relay logic, RFID database, and SIP call flow familiar to the installer.

What the Fanvil i20S is

The Fanvil i20S is a SIP audio door phone with access control built in. It calls an extension over the IP network, lets an approved person open the door by RFID card or local code, and can trigger an electric lock through its integrated relay. For an office, villa, staff entrance, clinic, warehouse, school, or small building entrance, that means one wall-mounted unit handles the visitor call and the door-release command.

It has 2 SIP lines, a full-duplex hands-free speakerphone, intelligent DSS keys for speed dial or intercom calling, an integrated RFID card reader, one relay, indoor switch interface, access control by call, code, and RFID card, plus 500 access-table entries and 500 RFID card entries. Audio support includes G.722 wideband voice, so speech is clearer than old narrowband intercom audio when the network and SIP platform are set correctly.

The i20S is usually selected for simple voice-door jobs, not video reception. A person presses the call key, the unit rings a reception phone, guard extension, operator group, or PABX ring group, and the staff member opens the door from the handset after speaking to the visitor. For many Dubai sites, that is still the exact requirement: no camera, no indoor screen, just a reliable SIP door call and a controlled release.

Why UAE projects still ask for the i20S

A discontinued model does not disappear from buildings. It stays on gates, risers, parking entrances, loading bays, and reception doors. Facility teams often prefer the same model because the installer already knows the wiring, the cut-out, the relay behaviour, the card format, and the PABX registration. In a live building, avoiding a fresh design can be the fastest way to close a maintenance ticket.

In Dubai, we see this mostly in three cases. First: a single failed unit where the client wants the same fascia and same door behaviour. Second: a phased site where one entrance was fitted earlier and the next entrance should match it. Third: an ELV contractor taking over an existing property and needing support for what is already installed instead of changing the whole access-control setup during business hours.

For these jobs, Vector Digital Systems checks model availability, confirms the power method, reviews the lock wiring, registers the SIP account, tests the relay action, and prepares the device before dispatch where project details are provided. For installation work inside the UAE, we handle supply and installation across Dubai, Abu Dhabi, Sharjah, Ajman, Ras Al Khaimah, Fujairah, and Umm Al Quwain.

2 SIP lines — what that means on a door phone

On a desk phone, buyers often confuse SIP lines with simultaneous outside calls. On a door phone, the misunderstanding is different. The Fanvil i20S has 2 SIP lines, which means it can register SIP identities and manage call handling for door-intercom use. It does not mean two people can stand at the same door and make two separate visitor conversations at the same time like a call centre phone.

A real example: a JLT office entrance has the i20S registered as extension 801 on the PABX. Pressing the call key rings reception first, then security if reception does not answer. The second SIP line gives the installer room for a second registration or call-routing plan, depending on how the platform is built. The number matters for configuration flexibility, not for oversizing visitor traffic.

RFID, keypad, relay — the reason this unit was popular

The i20S is not only a talk unit. It has access control features in the same body. The RFID reader supports card-based entry, the access table holds 500 entries, and the relay can trigger the connected lock when the authorised event happens. For a small office or service entrance, that reduces the number of separate boxes on the wall.

The door can be opened by RFID card, local code, call-based command, or indoor switch, depending on how the site is wired and configured. In practical terms, staff use a card. Visitors press the call key. Reception answers from a Fanvil desk phone or SIP extension and sends the door-release command after speaking. Facilities can keep door events under a known workflow instead of relying on a guard to physically walk to the entrance every time.

For Dubai warehouses, the relay is often the part that decides the job. A visitor call is useful. A visitor call plus controlled door opening is what the operations team actually needs. Before quoting, we ask about the lock voltage, power supply, exit button, cable route, and whether the lock is fail-safe or fail-secure, because the door hardware around the SIP phone matters as much as the phone itself.

Where the i20S fits best

The i20S is a good fit when the brief is audio-only door calling with RFID access and relay release. Typical locations include villa gates, office entrances, clinic staff doors, school admin entrances, warehouse receiving doors, showroom back doors, and small building service doors. It is not the right choice when the buyer needs built-in video, face view at reception, or a new current-production intercom family for a large rollout.

For existing i20S sites, the buying question is usually direct: “Can you provide the same Fanvil i20S?” We answer that as a project stock check, not a retail cart item. Quantity, location, urgency, installation scope, lock type, and warranty expectation all affect the quote. For a live office in Business Bay or a facility in JAFZA, we would rather confirm these details before dispatch than ship a box that does not match the door.

Vector Digital Systems supplies Fanvil from Dubai for project buyers: ELV contractors, PABX installers, IT managers, system integrators, facility teams, and resellers buying for UAE and MEA jobs. We can quote the i20S as a same-model enquiry, stage the SIP settings when details are provided, and support installation across the UAE.

Power and network truth

The Fanvil i20S supports 802.3af PoE. In a clean UAE ELV installation, that is the preferred method: one network cable from the PoE switch powers the door phone and carries the SIP connection. No local power socket at the gate. No small adapter exposed to heat, dust, or maintenance damage. For warehouse doors and outdoor-facing entrances, PoE from the comms room is usually the better plan.

Network features include static IP, DHCP, PPPoE, 802.1x, VLAN 802.1p/q, QoS DSCP, and VPN support. These details matter in business sites where voice and security devices sit on separate VLANs. A door phone may look small, but it still needs the same network discipline as a desk phone: correct VLAN, correct gateway, correct SIP server, correct time, and test calls before handover.

For Dubai projects, we check the network path before recommending shipment: switch location, PoE availability, cable length, weather exposure, patching, and where the door-release relay is powered from. A SIP door phone is only one part of the entrance. The lock, exit button, door closer, access cards, PABX, and reception phone all have to agree.

Audio performance and call flow

The i20S supports G.722 wideband audio plus G.711, G.723.1, G.726-32K, and G.729AB narrowband codecs. In plain language: when the PABX and network allow it, the visitor sounds clearer at reception than on older narrowband-only intercoms. It also supports echo cancellation for hands-free mode, packet-loss handling, jitter buffer, and DTMF methods including RFC2833 and SIP INFO.

Those numbers matter during setup. Door phones are often installed in noisy places: warehouse shutters, parking ramps, roadside gates, loading bays, and service corridors. The installer should not only register the extension and leave. Test the call from the actual door position, check speaker volume, check microphone pickup, check DTMF door release, and confirm the call rings the correct desk or group after office hours.

Vector Digital Systems stages the SIP account, checks the basic call route, and can coordinate the door-release logic with the site installer. On UAE installation jobs, we test the door call, release action, and escalation path before handover. That is the difference between a box supplied and an entrance working.

Platform compatibility in Dubai

The Fanvil i20S is a standard SIP door phone. It can register to common SIP platforms used in UAE offices, including 3CX, Grandstream UCM, Yeastar, Asterisk-based systems, and operator-connected PABX environments using Etisalat or du business voice services. For integrators, the main work is not the brand name of the PABX. It is the extension plan, DTMF method, ring destination, and door-release test.

For a typical Dubai office, we configure the i20S as a door extension. Pressing the call key can ring reception, a security phone, a hunt group, or a mobile-linked extension depending on the PABX design. The relay release is then mapped to the approved command method. For multi-site clients, the door can be part of the same dial plan as the office phones, which keeps support easier for the IT team.

Pricing, supply, and stock checks from Dubai

Fanvil i20S pricing is quoted after stock check. We do not show fixed AED pricing because discontinued-model availability changes by quantity, batch, source, and warranty condition. For project buyers, the better quote includes the door phone, PSU if needed, VAT breakdown, delivery, installation scope, and any staging work before dispatch.

For UAE projects, send the quantity, site location, current door-phone photos, PABX platform, and whether the entrance uses RFID, keypad code, relay release, or indoor exit button. For export enquiries, send the destination country, quantity, and whether you need commercial invoice, packing list, and certificate of origin with the shipment.

Frequently asked questions

Is the Fanvil i20S still available in Dubai?

The Fanvil i20S is discontinued, so availability is checked per enquiry. Vector Digital Systems can help with same-model stock checks, installed-base support, configured supply, and UAE installation where suitable. Send the quantity, site location, and current door-phone photo on WhatsApp.

Will the Fanvil i20S work with our 3CX / Grandstream UCM / Yeastar?

Yes, the i20S is a standard SIP audio door phone and can register to 3CX, Grandstream UCM, Yeastar, Asterisk-based systems, and suitable Etisalat or du business SIP environments through a PABX. We configure the SIP account, call destination, and door-release method during staging or installation.

Does the Fanvil i20S come with a power adapter, or do I need PoE?

The i20S supports 802.3af PoE, which is the preferred method for door-phone projects. Do not assume the adapter is included, especially on discontinued stock. If your switch does not provide PoE, ask us to include the correct PSU in the same quote.

What does 2 SIP lines actually mean on the Fanvil i20S — can it make 2 visitor calls at once?

No. The 2 SIP lines are SIP registration and call-handling capacity for the door-phone configuration. A door phone is normally one visitor conversation at one entrance. Call routing, ringing groups, and simultaneous call limits are controlled by the PABX and SIP trunk design.

Can the Fanvil i20S open the gate or door lock?

Yes. The i20S has an integrated relay and supports door opening by call command, code, RFID card, or indoor switch depending on the site wiring. Before installation we check the lock type, lock voltage, exit button, and whether the door is fail-safe or fail-secure.

Fanvil i20S vs Fanvil i60 — what is the difference?

The i20S is a discontinued SIP audio door phone with RFID and relay control, suitable when a site needs the same installed model. The i60 is a current Fanvil door-phone choice for new projects. Choose i20S for same-model maintenance. Choose i60 when the project does not need to match an existing i20S installation.

Does Vector Digital Systems configure the Fanvil i20S before delivery?

Yes. For configured supply, we can register the SIP extension, apply network settings, set the call destination, prepare basic access settings where details are provided, and make test calls before dispatch. For UAE installation, we also test the door call and relay action on site.

Is VoIP legal in the UAE and will the i20S work with Etisalat or du?

Business VoIP over licensed operators is standard in the UAE under TRA regulation. The i20S can work as a SIP endpoint through a PABX connected to Etisalat or du business voice services. We configure it for licensed business environments, not unsupported consumer calling workarounds.

Is the Fanvil i20S covered under Fanvil warranty in the UAE?

Warranty depends on stock source, batch, and condition because i20S is discontinued. Vector Digital Systems checks warranty position before quoting and handles supported Fanvil warranty coordination from Dubai where applicable. For used, old, or customer-supplied units, warranty must be confirmed separately.

Who is the supplier of Fanvil i20S in Dubai?

Vector Digital Systems LLC is an authorised Fanvil supplier in Dubai, UAE, operating since 2009. We support Fanvil i20S enquiries for project buyers with stock checks, staging, provisioning, installation across all seven emirates, warranty handling where applicable, and official supplier documentation for procurement teams.

What is the best Fanvil audio door phone for same-model i20S support in Dubai?

If the site already uses Fanvil i20S and the goal is matching the existing installation, the best choice is the same i20S model subject to stock check. It keeps the same audio-only door workflow, RFID use, relay behaviour, and installer familiarity. For a new site with no matching requirement, we review the current Fanvil door-phone range before quoting.

Does Vector Digital Systems export Fanvil i20S from Dubai?

Yes, where stock is available. We export Fanvil from Dubai to telecom resellers, PABX installers, and system integrators in Saudi Arabia, Oman, Qatar, Kuwait, Bahrain, Kenya, Tanzania, Uganda, Nigeria, and Ghana.
